HV73518-Channel, В±70V, 3A Programmable High-VoltageUltrasound-Transmit BeamformerFeatures General Description The HV7351 device is an 8-channel programmablehigh-voltage ultrasound-transmit beamformer. Eachchannel is capable of swinging up to В±70V with anactive discharge back to 0V. The outputs can sourceand sink up to 3.0A to achieve fast output rise and falltimes. The active discharge is also capable of sourcingand sinking 3.0A for a fast return to ground. The topology of the HV7351 will significantly reduce the numberof I/O logic control lines needed. Eight Channels with Return-to-Zero (RTZ)Up to В±70V Output VoltageВ±3.0A Output CurrentStores up to Four Different PatternsIndependent Programmable Delays80-lead Single 11 x 11 mm VQFN Package Applications Each pulser has four associated 64-bit shift registersfor storing predetermined transmit patterns and a 10-bitdelay counter for controlling the transmit time. One offour arbitrary patterns can be transmitted with adjustable delay, depending on the data loaded into theseshift registers and the delay counter. The delay countercan be clocked up to 200 MHz, allowing incrementaldelays down to 5 ns. Medical Ultrasound ImagingNDT, Non-Destructive Testing ...
